the flexible protection pad 61 is connected to the end part of the top plate 53 in a sliding manner, so that a layer of isolation can be formed between the top plate 53 and the frame, the paint on the frame is further protected, and meanwhile, when the retraction stroke of one of the push rods 52 is too long, the pressure applied to the adjacent push rod 52 is dispersed, so that the clamping force of the second piston rod 14 on the frame is more uniform; when the flexible protection pad 61 is squeezed by the frame to retract towards the interior of the second piston rod 14, the elastic sheet 7 can enable the ejector rod 52 to slightly vibrate, and dust on a contact surface of the frame and the flexible protection pad 61 is swept away, so that the problem that the frame and the flexible protection pad 61 slide is solved; when the wire collecting wheel 42 tensions the isolation pad 43, the second suction cup 83 can be tightly attached to the surface of the piston bag 2, and meanwhile, the first suction cup 81 can be sucked to the bottom of the frame in the process of contacting the bottom of the frame, so that the problem that the frame can slide on the top of the grabbing arm 1 is further reduced; the protection pad 9 is arranged between the first piston rod 12 and the side wall of the grabbing arm 1, so that the problem that impurities on the frame fall into the cavity of the grabbing arm 1 can be reduced, and the first piston cylinder 11, the first piston rod 12, the second piston cylinder 13 and the second piston rod 14 can be used for a long time without easily causing the problem of clamping; air guide hole 91 is formed in protection pad 9, so that gas in the cavity of grabbing arm 1 can be normally discharged to the outside of the cavity of grabbing arm 1, when second piston rod 14 and first piston rod 12 are prevented from being extruded simultaneously, the gas in the cavity cannot be timely discharged, and the first piston rod 12 and second piston rod 14 are prevented from retracting to cause problems, flexible gasket 92 is arranged in air guide hole 91, impurities falling on the frame can be prevented from entering the cavity of grabbing arm 1 from air guide hole 91, the cavity of grabbing arm 1 is kept clean and tidy, and service life is prolonged.
